Massive final-day registration in PA

From NBC/NJ's Matthew E. BergerPHILADELPHIA -- While a final number may not be available for a few weeks, the Pennsylvania Department of State has released an update on the number of people registered to vote in the April 22 Democratic primary here. And it shows a massive registration effort on the final day of eligibility.

The state now has 4,119,213 registered Democrats. Since March 24, the last day of eligibility for the primary election, the state has received 33,281 new Democratic registrations and 45,977 party changes to the Democratic Party. The secretary of state's office is still accepting new registrations and party switches that were postmarked by the deadline.

State officials said the activity on the final day was intense, and these new numbers likely include large swaths of registrations that were collected by both the Obama and Clinton campaigns and submitted just before the deadline.

Since the first of the year, the state has received 101,499 new Democratic applications and 132,688 switches to the Democratic Party.

By contrast, the Republican Party in Pennsylvania now stands at 3,197,586 people. Only 32,191 citizens have joined the Republican roles and 13,937 have switched to the GOP since January 1.
